Washington, July 31 (ANI): Children as young as nine years old can perform Cardiopulmonary resuscitation (CPR) when needed, according to a study.

The study found that although the smallest may lack the requisite strength, the knowledge of how to perform basic life support is well retained by young children.

A research team led by Fritz Sterz, from the Medical University of Vienna in Austria, studied 147 schoolchildren who had received six hours of life support training.

Upon examination four months after the training, 86 percent of kids performed CPR correctly.

“The usefulness of CPR training in schools has been questioned since young students may not have the physical and cognitive skills needed to perform such complex tasks correctly. We found that, in fact, students as young as 9 years are able to successfully and effectively learn basic life support skills. As in adults, physical strength may limit depth of chest compressions and ventilation volumes, but skill retention is good,” said Sterz.

The skills taught to the children included automatic defibrillator deployment, providing CPR, usage of the recovery position, and calling for the emergency services.

For the critical skills of CPR and mouth-to-mouth resuscitation, BMI was the factor that had the biggest influence on depth of compressions and amount of air inhaled.

Age did not play a role, indicating that a well-built nine-year-old could be as capable as an older child.

The researchers concluded: “Given the excellent performance by the students evaluated in this study, the data support the concept that CPR training can be taught and learnt by school children and that CPR education can be implemented effectively in primary schools at all levels. Even if physical strength may limit CPR effectiveness, cognitive skills are not dependent on age, and with periodic retraining, children’s performance would likely improve over time.”
